It was associated with epigastric tenderness, bilious vomiting and jaundice. He had been intermittently experiencing these symptoms for the last 1\u2009year. No known comorbid. Ultrasound showed a poorly visualised heterogeneous focus at porta hepatis; considering poor visualisation, this might represent an enlarged calcified lymph node or cystic duct calculus causing extrinsic compression or a large sludge ball within the common bile duct (CBD), leading to dilatation of common hepatic duct and intrahepatic biliary system. Subsequent magnetic resonance cholangiopancreatography revealed a focal saccular dilatation of middle part of CBD, a type I-B choledochal cyst, large heterogeneous focus seen within it representing choledochocystolithiasis. Later, CT was performed for further characterisation of surrounding anatomy and pathology, which confused the appearance of choledochocystolithiasis for Mirizzi syndrome. Later, surgery and histopathology confirmed type I-B choledochocystolithiasis and chronic cholecystitis.<\/jats:p>","DOI":"10.1136\/bcr-2017-219582","type":"journal-article","created":{"date-parts":[[2017,6,24]],"date-time":"2017-06-24T23:20:08Z","timestamp":1498346408000},"page":"bcr-2017-219582","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["A large choledochocystolithiasis mimicking Mirizzi syndrome"],"prefix":"10.1136","volume":"2017","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0082-9217","authenticated-orcid":false,"given":"Mustafa Belal Hafeez","family":"Chaudhry","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muhammad","family":"Azeemuddin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muhammad Rizwan","family":"Khan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Om","family":"Parkash","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2017,6,24]]},"reference":[{"key":"2025042712021599000_2017.jun24_2.bcr-2017-219582.1","doi-asserted-by":"publisher","DOI":"10.1002\/aja.1000380202"},{"key":"2025042712021599000_2017.jun24_2.bcr-2017-219582.2","first-page":"656","article-title":"Choledochal cysts in adults: clinical management","volume":"96","author":"Nagorney","year":"1984","journal-title":"Surgery"},{"key":"2025042712021599000_2017.jun24_2.bcr-2017-219582.3","unstructured":"Choi BI , ed.
